SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 295,613, dated March25, 1884.

Application filed August 11, 1883. (No model.)

To ctZZ whom it may concern:

Be it known that I, SAMUEL W. BARR, of Mansfield, Richland county, Ohio,have invented a new and useful Improvement inSulky- 5 Plows, whichimprovment is fully set forth in the following specification, referencebeing had to the accompanying drawings.

My invention relates to that form of sulky' or riding plow in which theplow is constructed to conform to the attachments and the attachmentscombined with the plow in such a way as to form a complete machine.Neither can be separated without leaving the other valueless.

1 5 My invention consists, mainly, in a combination of levers forraising the point of the plow by means of a vertical hinge at the frontend of the plow-beam, and in a horizontal hinge at the end of the beamto allow the team to turn easily at corners and pull the plowaroundalso, in a combination draft-rod for gaging the depth of a plow.

Figure 1' is a side view of my sulky-plow, showing the combinationdraft-rod. Fig. 2 is a top view, showing the relative position of thewheel is, beam, and mold-board. Fig. 3 represents a portion of the beamand a por, tion of the tongue connected by the hinges, and is a viewfrom the opposite side of the hinges of Fig. 1.

Similar letters refer to similar parts.

The beam A of my.plow sets nearly over the center, and is firmly boltedat its rear end to a cast base that holds the share and mold-board. Thespindle of the wheel K, Fig. 2, is secured to a rear projection of thisbase, and the wheel runs on this'spindle with its face side against the'bank of the furrow, and forms one side of the sulky, a portion of thelandside, and carries the plow. The wheel is set with its front close tothe mold-board, and hasasmall flange on the land-side edge of its rim toprevent slipping sidewise. Its diameter is such as to make the plow ofusual length. The bracket P, Fig; 2, is permanently secured to the beam,and has one end drilled and bent down at right angles to its side, andthe lower end is thrown out till its face is parallel with the outsideof the segment Q. The lever g is formed with a disk at its fulcrum, andhas a with its slot, is upon the short arm at nearly right angle, to theend of which the spindle for the wheel Z is riveted.

A bolt holds it to the bracket P, and when the plow is doing its workthe lever 9 stands nearly perpendicular and the wheel Z is opposite thewheel K. The lever g is provided with thumb-lever, spring-pawl, &c., forengaging the segment. The lever F, Fig. ljis formed with a circularplate at its fulcrum, and a curved short arm, J, having a slot nearlyits whole length. The lever is provided with the usual devices foradjusting it. The notched plate E has two points on the opposite side,that rest on the beam to keep it from turning, and is held to the beamby the same bolt that 6 holds the lever F. The short arm of the lever,cam principle, and when the lever is thrown forward the bolt of the barB rides up the slot and lifts the bar. The bar B extends to the end ofthe beam, and forms one half of the hinge e, the other half of which isbolted to the end of the tongue D.

A bolt, W, through the end of the beam and bar B forms the verticalhinge at the endof the plow-beam. The bar B and tongue, connected by thehinge c, constitute a rigid line from the neck-yoke of the team to thelever F, and when the lever is thrown forward the end of the bar israised, and the point of the plow also. In this operation the weight ofthe end of the beam, double-trees, &c., falls on the wheel Kandneck-yoke.

Fig. 3 represents a portion of the beam A and the rear end of thetongue, and is a view from the opposite side of Fig. l. A top view ofthis arrangement is shown at m o a, Fig. 2. The hinge-bar m is securedto the side of the tongue by the same bolts that hold the front portionof the hinge c, Fig. 1. The strap a has a notch in its upper edge tocatch in the 0 staple 0, and is knuckled with the bar m just in front ofthe hinge c. A spring, 15, knuckled with the bar at at the same point,slides through the staple. 0 below the strap N, and keeps the strapagainst the upper part of the staple. The 9 5 I staple 0 is strong andfastened firmly to the beam A, and is of such size as to give said strapthe requisite play. This check-hinge holds the tongue and beam rigidlyin line, but when turning at corners the strapN is pressed I00 U down bythe drivers foot, disengaged, and the team can walk around and turn theplow while in the ground.

The side view of my sulky-plow, Fig. 1, shows a new form, of draft-rodfor gagingthe depth of a plow. The rod S is bolted to the beam A abovethe mold-board, and has a thread out on its front end several inchesback for a nut. A long clevis, H, with a hole in its end, is placed onthe rod, and a spiral spring, I, of suitable strength and size, is puton between the sides of the clevis, and the nut turned on the rod. Theclevis extends forward on either side of the curved beam projection R,and has. a bolt in the front end for a hitch. A small roller is placedbetween the sides of the long clevis to move along the lower edge of theprojection R. A pin in the lower end of the deep, and the plow is thrownup by any obstruction, the spring will expand and draw the roller up thecurved projection R, and turn the point of the plow down. On the otherhand, if the plow cuts seven inches deep, more power will be required todraw the plow, the spring will be compressed, and the roller Havingfairly and fully described the sev- 1 eral parts and functions of mysulky-plow, I wish to secure by Letters Patent the followmg:

1. The combination, in a sulky-plow, with the pivoted bar B, of thetongue D, the hingeplate 0, the hinged bars M N, staple O, and spring T,substantially as shown and described.

2. The plow-beam A, pivoted tothe bar 13, and the curved projection R,in combination with the spring draft-rod H, roller h, and draftclevis,substantially as set forth.

3. The combination, with the pivoted bar B, having 'pin 11, of the leverF, having the curved slotted arm J, the rack E, plow-beam A, and wheelK, substantially as shown and described.
